 2026-07-11 11:04:47 -07:00
LC a90a7dbec7 x32/FD: Fix readahead upper offset type 
This should be a uint32_t

LC 2250bd58a2 x32/FD: Deduplicate guest and host fd set management 
Same behavior, but less copy pastey
 2026-07-11 13:23:19 -04:00
LC 126be45ed1 x32/FD: Correct total word calculation in select() variants 
Previously this would result in a larger amount of words specified than
necessary.

e.g. Given nfds = 1:

With AlignUp(1, 32) / 4, we'd end up with supposedly eight words, when it
should only be one word.

On the other extreme, given a full fd set of 1024 fds, then we'd end up
with 256 words, when it should only be 32.

LC e021a55abd BPFEmitter: Amend instruction class checking in HandleStore() 
This was previously checking for a load class, which would result in ST
clobbering the index register.
 2026-07-11 12:26:11 -04:00
LC 2ad6254894 x64/Thread: Amend faulting copy handling related to LDTs 
CopyToUser doesn't return the number of bytes copied, but rather returns
0 to indicate success, otherwise a fault has occurred (and the SIGSEGV
handler has set X0 to EFAULT)

LC f4c50105ba x32/Thread: Move writability check around in waitpid 
Same behavior, but catches the write before it actually occurs.

It's been ten months, a bit longer than than I was expecting to keep
this around. Go ahead and remove it now.

Tony Wasserka 54236df6e0 CodeCache: Record main executable bitness in code map 
Code maps already contain the main executable they were recorded from, so
it's convenient to capture the executable's bitness along the way.

Tony Wasserka d3d735370f FEXOfflineCompiler: Fix improper syscall ABI on WoA 2026-07-06 15:16:30 +02:00
Egor Lazarchuk 1eb5abb8db Allocator: rename DetermineVASize to GetHostVABits 
`DetermineVASize` does not return the size of VA, but the number of bits
it can use. Change the naming to make it more self explanatory.
In the mean time also move `HostVASize` global into `GetHostVABits`
since it is not and should not be used directly.

FEXServerClient: Workaround sun_path 108 byte limit
 2026-07-02 04:03:48 -04:00
Ryan Houdek 6bf0db7df6 FEXServerClient: Workaround sun_path 108 byte limit 
We really don't want to do this, but in the case that the AF_UNIX path
is longer than the 108-byte limit that sun_path provides we don't really
have a choice. The alternative choice would be to switch /entirely/ away
from AF_UNIX and instead use pipes. We need a bandage fix for now, so
throw the socket in to a temp folder if the path is too long.

Ryan Houdek 5bde4d875a FEXOfflineCompiler: Fixes HostFeature detection under Win32 
CPUFeature detection is marginally different between Linux and Windows.
FOC was only using the Linux path which had two broken things happening
to it.
- Feature detection was incorrect and enabling/disabling features
  differently from wow64/arm64ec .dll files
- HostType was being set as Linux even though it was generating code for
  WINE

Ensure that when built for Win32 that it uses the correct feature
fetching.

One thing that is still incorrect is that 64-bit or 32-bit is determined
at compile time on win32, whereas the Linux side parses an ELF and
determines bitness at runtime. This doesn't fix that remaining problem
there.
